During the manufacture of crankshaft for
Volvo heavy vehicles, oil holes drill is essential for lubrication purpose.
Drill bits are used for the above drilling purpose. The drill bits break due to
abnormalities such as coolant pressure, drill cutting edge blunt, rigidity etc.
To eliminate this breakage issue, some of the essential parameters such as
point angle, honing angle, lip height etc. of drill nomenclature as well
another factor like coolant, speed, machine malfunction etc. are modified. This
project deals with breakage analysis of existing drill bit due to vertical
machine parameters and constituent conditions of the machine during drilling.
